This document describes the steps on how to resolve the issue on propagating deployment changes on a ViewApp or any object, to its instances. In this case the issue came following a troubleshooting done on a corrupted ViewApp. A ViewApp layout pertaining to the historical alarms got corrupted. The client only showed the historical events, and no alarms were shown. In this case, the ViewApp layout was changed, and another layout was configured. The focal point of this document is: 1. All check-ins done prior to the deployment. 2. The deployment to occur without error.
